This AC provides guidance and standardized methods for meeting the training requirements outlined in Title 14 of the Code of Federal Regulations (14 CFR) Part 91 Subpart N, Mitsubishi MU-2B Series Special Training, Experience, and Operating Requirements, for Mitsubishi MU-2B aircraft. The new part 91 subpart N mandates training, experience, and operating requirements to ensure the highest level of operational safety for the Mitsubishi MU-2B series airplanes. This AC describes an acceptable means, but not the only means, of complying with the requirement that all training and checking for the MU-2B aircraft must be conducted in accordance with a Federal Aviation Administration (FAA)-approved training program. This AC is not mandatory and does not constitute a regulation; however, it may be used by training providers to meet the requirements of part 91 subpart N. Training providers may also use this AC as a reference for developing their own MU-2B training programs to submit for FAA approval pursuant to the requirements of part 91 subpart N. **2 BACKGROUND.** 2.1 SFAR 108 Issuance. In 2008, the FAA published SFAR 108 to mandate flight training and experience requirements for operators of the Mitsubishi Heavy Industries, LTD. (MHI) MU-2B twin turboprop aircraft. The rule became effective in 2009 and does not have an expiration date. The flight training and experience requirements were based on an FAA safety evaluation of the aircraft, which has unique control surfaces and characteristics. There is a fleet of approximately 300 aircraft operating today in accordance with 14 CFR parts 91 and 135. In the 20 years leading up to SFAR 108, the MU-2B series aircraft experienced 80 accidents with 40 fatalities. Since the effective date of SFAR 108, there have only been two fatal accidents. In addition to experience and annual training requirements for pilots, SFAR 108 mandates training curriculum and flight profiles for operators and training providers. 2.2 SFAR 108 Evaluation. Following the issuance of SFAR 108 on February 5, 2008, with a compliance date of February 5, 2009, Mitsubishi Heavy Industries America, Inc. (MHIA) began an evaluation to identify errors in flight profiles published in SFAR 108. At that time, MHIA notified the FAA of at least one error in procedure in the One Engine Inoperative Maneuvering/Loss of Directional Control (Minimum Controllable Airspeed with the Critical Engine Inoperative (VMC) Demonstration) profile. ### Page 2 2.3 Continuous Descent Final Approach (CDFA) Use. Since the publication of SFAR 108, the FAA has approved the use of CDFA procedures in all training programs, including the training programs for the MU-2B. The MU-2B FAA Flight Standardization Board (FSB) subsequently included CDFA profiles in its FSB Report for use in MU-2B training programs. Because the FAA had not included CDFA procedures in SFAR 108, pilots were not permitted to train on these procedures or operate the aircraft consistent with them. 2.4 Revision of Procedures and Programs. In 2012, the FAA revised its stall recognition and recovery procedures for all aircraft and all training programs by removing the emphasis to ensure a “minimum loss of altitude” when performing stall training maneuvers and by emphasizing a positive reduction in angle of attack (AOA) procedure as the proper stall recovery method (refer to the current edition of AC 120-109, Stall Prevention and Recovery Training). The FAA also introduced the use of “startle factor” training through the use of the autopilot during stall recognition and recovery practice in all aircraft training programs. However, until now, the FAA had not included the “startle factor” training requirements in MU-2B training programs. 2.5 Flight Training Profiles. The MU-2B flight training profiles included in Appendix A, MU-2B Training Program, of this AC are now consistent with FAA policy on stall recognition and recovery procedures essential to proper MU-2B training and safety of flight. **3 APPLICABILITY.** 3.1 Who Does This AC Apply To? Part 91 subpart N and this AC apply to all persons who operate the Mitsubishi MU-2B series airplane, including those who act as pilot in command (PIC), act as second in command (SIC), or other persons who manipulate the controls while under the supervision of a PIC. Part 91 subpart N and this AC are also applicable to those persons who provide training and checking conducted in the aircraft, as well as currency and experience for the Mitsubishi MU-2B series airplane. A single standard of training, checking, and currency to all MU-2B operations, including part 91 operations, is necessary to achieve safety. The part 91 subpart N requirements are in addition to the requirements of 14 CFR parts 61, 91, 135, 141, and 142. 3.2 What is the Approval Process for a Training Program? Part 91, § Section 91.1705, Required Pilot Training, states that only training programs approved by the Administrator may be used to satisfy the standards of part 91 subpart N. Part 91 subpart N, Preamble Section III, Discussion of Final Rule (81 FR 61583), states that training providers may submit the most current version of Appendix A of this AC for training program approval. Appendix A specifies a training program curriculum that meets the requirements of § 91.1705(h) and meets the standards for FAA approval. Appendix A may be electronically submitted to the FAA as a proposed training program for approval. Alternate means of compliance must also be approved by the FAA. If alternate compliance is sought, air carriers under part 135, program managers under part 91 subpart K (part 91K), and parts 91, 141, and 142 training providers (i.e., operators and training providers) must demonstrate that the proposed alternate means meets the ### Page 3 3 standards of part 91 subpart N. Analysis, demonstrations, proof of concept testing, Differences documentation, or other evidence may be required. If the means of compliance in Appendix A is submitted as a proposed training program, it must conform to it in all significant respects. 1. The proposed MU-2B training program must include factory type design Differences as specified in part 91 subpart N, as applicable to the training and/or operation. The FAA recommends that where MU-2B Differences in addition to factory type design differences are applicable to training and/or operation, the Differences specified in the MU-2B series FSB Report be included in the training provider’s proposed MU-2B training program. 2. The Administrator may require revision of an approved MU-2B training program at any time. An operator or training provider must present its approved training program and FAA approval documentation to any representative of the Administrator, upon request. 3. In order to provide subpart N of part 91-compliant instruction under an approved training program, each MU-2B qualified instructor must be an authorized instructor of an operator under parts 91K, 135, 141, and/or 142, or be named on the letter of authorization (LOA) approving an MU-2B training program for a part 91 training provider.1 3.2.1 Operators and Training Providers Under Parts 91K, 135, 141, and 142. 3.2.1.1 Proposed Training Program Submission. Operators and training providers may submit their proposed training program to their principal operations inspector (POI) or Training Center Program Manager (TCPM) for approval and inclusion in their approved training curriculum. 3.2.1.2 MU-2B Training Program Submission. Operators and training providers may submit an MU-2B training program that meets the content requirements of part 91 subpart N and include any Differences specified in the MU-2B series FSB Report applicable to the operator’s MU-2B training. This proposed MU-2B training program may be submitted in accordance with existing FAA approval process guidance for training programs. 3.2.1.3 MU-2B Instructors. MU-2B qualified instructors are authorized instructors in accordance with the operator or training provider’s approved training program. 3.2.2 Part 91 Training Providers. 3.2.2.1 MU-2B Part 91 Subpart N Training. All MU-2B part 91 subpart N training, including those conducted under part 91, must be conducted in accordance with an FAA-approved training program. The term “part 91 training provider” 1 The term “part 91 training providers” refers to training providers providing training under part 61 authority in a part 91 operation. ### Page 4 4 refers to training conducted under part 61 authority in a part 91 operation. Part 91 training providers may submit a proposed training program to their jurisdictional FAA Flight Standards District Office (FSDO), who will then forward the proposed training program to the Flight Standards Service (AFS) General Aviation and Commercial Division (AFS-800) for approval. With AFS-800 approval, the jurisdictional FSDO will issue an LOA to the part 91 training provider, if it is determined that the proposed training program meets the standards of part 91 subpart N. Training programs approved for part 91 training providers will be approved for 24 calendar-months, unless superseded or rescinded prior to the approval expiration date. 1. Any proposed MU-2B training program that differs substantially from the training program curriculum presented in Appendix A of this AC must be coordinated with AFS-800 and the Kansas City Aircraft Evaluation Group (AEG) prior to FAA approval. 2. With AFS-800 approval, the jurisdictional FSDO will issue an LOA to the part 91 training provider, if it is determined that the proposed training program meets the standards of part 91 subpart N. 3. Means of compliance must conform to Appendix A in all significant respects. Proposed training programs that differ from the program described in Appendix A may be submitted as an alternative means of compliance if it meets the standards of part 91 subpart N. 3.2.2.2 Qualified Instructors. For part 91 training providers, MU-2B qualified instructors are listed by a certified flight instructor (CFI) certificate on the LOA approving the part 91 subpart N MU-2B training program. The FAA may request reporting of MU-2B-qualified instructor activity when issuing LOA-affiliated CFIs, similar to the reporting used for the renewal of a CFI certificate. Each MU-2B-qualified instructor may hold an LOA for their own FAA-approved MU-2B training program, or multiple MU-2B-qualified instructors may be listed on the same LOA for one FAA-approved MU-2B training program. **4 RELATED DOCUMENTS.** 4.1 What Are the Related Documents (current editions)? • Title 14 CFR Part 91 Subpart N. • AC 120-108, Continuous Descent Final Approach. • AC 120-109, Stall Prevention and Recovery Training. 4.2 Does This AC Cancel Any Prior ACs?

ORIGINAL SIGNED by /s/ John Barbagallo Deputy Director, Flight Standards Service ### Page 7 Appendix A A-1 APPENDIX A. MU-2B TRAINING PROGRAM A.1 MU-2B General Training Requirements. A.1.1 What Are the General Training Requirements for the Mitsubishi MU-2B? A.1.1.1 Training Requirements. The Mitsubishi MU-2B training program consists of both ground and flight training. The minimum pilot training requirement hours are shown in Table A-1, Minimum Ground Instruction Training Hours, for ground instruction and Table A-2, Minimum Flight Instruction Training Hours, for flight instruction. An additional ground training requirement for Differences Training is shown in Table A-3, Minimum Differences Training Hours. A.1.1.2 Training Credit. The MU-2B is certificated by the Federal Aviation Administration (FAA) as a single-pilot airplane. No training credit is given for second-in-command (SIC) training and no credit is given for right seat time under this program. Only the sole manipulator of the controls of the MU-2B airplane, flight training device (FTD), or Level C or D simulator can receive training credit under this program. A.1.1.3 Training Program Differences. The training program references the applicable MU-2B Airplane Flight Manual (AFM) in several sections. There may be differences between sequencing of procedures found in the AFM’s procedures sections and the checklists, procedures, and techniques found within this training program. Title 14 CFR part 91 subpart N requires that if there are any differences between the AFM’s procedures sections (Normal, Abnormal, and Emergency) and the training and operating requirements of part 91 subpart N, the person operating the airplane must operate the airplane in accordance with the training specified in part 91 subpart N and an approved MU-2B training program.

A.2.1 Level A Training. Training that is conducted through self-instruction by the pilot. No minimum training program hours apply. Level A Differences are those Differences which need awareness, but which have no effect on procedures. A.2.2 Level B Training. Training that is conducted in the classroom environment with the aid of a qualified instructor who meets the requirements of part 91 subpart N, applicable as specified in § 91.1705(h)(4). Level B Differences are of great enough degree to require formal training, but are not of great enough degree to require systems integration training, such as aircraft systems Differences that have only minor procedural Differences. A.2.3 Level C Training. Training that is accomplished in an FAA-approved Level 5, 6, or 7 FTD or simulator. In addition to the basic FTD requirements, the FTD must be representative of the MU-2B cockpit controls and be specifically approved by the FAA for the MU-2B airplane for Level C Initial, Transition, Requalification, or Recurrent Training. Level C Training is applicable for recurring MU-2B training and to each model modified from factory type design where the change meets the definition for Level C Differences. Level C Differences are those Differences of great enough degree to require a systems integration training, but that are not of great enough degree to require actual flight training to ensure proficiency, such as installation of an Area Navigation (RNAV) System. Level C Initial Differences Training must include a Training Course Final Phase Check of items affected by the differences in type design. A.2.4 Level D Training. Training that must be accomplished in the MU-2B airplane or approved MU-2B simulator. Level D Training is applicable to each model modified from factory type design where the change meets the definition for Level D Differences. Level D Differences are those Differences for which flight training is necessary to ensure proficiency, such as installation of an electronic flight instrument system (EFIS) with a primary flight display (PFD) format. Level D Initial and Recurrent Differences Training must include a Training Course Final Phase Check of items affected by the differences in type design. A.2.5 Level E Training. Training that must be accomplished in the MU-2B airplane, Level C simulator, or Level D simulator. Level E Training is applicable to the MU-2B aircraft in relation to other Airplane Multiengine Land (AMEL) aircraft. A.3 MU-2B Ground Training Curriculum Contents. A.3.1 What Are the MU-2B Required Ground Training Tasks? All items in the ground training curriculum must be covered. The order of presentation is at the discretion of the instructor. The student must satisfactorily complete a written or oral exam given by the training provider based on this MU-2B training program. ### Page 10 Appendix A A-4 A.3.1.1 Aircraft General. 1.

Note: In all cases, a pilot must show complete mastery of the aircraft, with the outcome of each maneuver or procedure never seriously in doubt. A.4.4 Maneuvers and Procedures. All flight training maneuvers and procedures must be conducted, as applicable to the MU-2B and each type of operation involved. A.4.4.1 Preflight. 1. Preflight Inspection. The pilot must: • Conduct an actual visual inspection of the exterior and interior of the airplane, locating each item and explaining briefly the purpose of inspecting it; and • Demonstrate the use of the appropriate checklist, appropriate control system checks, starting procedures, radio and electronic equipment checks, and the selection of proper navigation and communications radio facilities and frequencies prior to flight. 2. Taxiing. This maneuver includes taxiing in compliance with instructions issued by the appropriate air traffic control (ATC) facility or by the person conducting the check. 3. Pre-Takeoff Checks. The pilot must satisfactorily complete all pre-takeoff aircraft systems and powerplant checks before takeoff. A.4.4.2 Takeoff and Departure. 1. Normal. One normal takeoff, which, for the purpose of this maneuver, begins when the airplane is taxied into position on the runway to be used. 2. Instrument Takeoff. Takeoff with simulated instrument conditions at or before reaching an altitude of 200 feet above the airport elevation and visibility of 1800 Runway Visual Range (RVR). ### Page 24 Appendix A A-18 3. Crosswind. One crosswind takeoff, if practical, under the existing meteorological, airport, and traffic conditions. 4. Powerplant Failure. One takeoff with a simulated failure of the most critical powerplant at a point after liftoff speed (VLOF). In the MU-2B airplane, all simulated powerplant failures must only be initiated when the person conducting the training or checking determines that it is safe under the prevailing conditions. The instructor must assure that the power lever does not move beyond the flight idle gate. 5. Rejected Takeoff. A rejected takeoff performed in an airplane during a normal takeoff run after reaching a reasonable speed, determined by giving due consideration to aircraft characteristics, runway length, surface conditions, wind direction and velocity, brake heat energy, and any other pertinent factors that may adversely affect safety or the airplane. 6. Area Departure. Demonstrate adequate knowledge of departure procedures, establishing appropriate ATC communications, and following clearances. A.4.4.3 Flight Maneuvers and Procedures. 1.

When Differences Training is required, it must be consistent with this training program. Differences Training is required for operation of more than one factory type design MU-2B model, as specified in Table A-3. Differences Training is not required if Initial, Transition, Requalification, or Recurrent Training is conducted in each model and/or modified model of the MU-2B operated. The following Differences Training requirements do not account for every modification to MU-2B aircraft that should be trained for pilot proficiency. For these identified Levels B, C, and D Differences, and any similarly applicable Differences, an MU-2B pilot must be trained to safely operate MU-2B aircraft with applicable equipment with sufficient proficiency to meet the requirements of the Training Course Final Phase Check. Levels C and D Initial Differences and Level D Recurrent Differences must include a record of the Training Course Final Phase Check for evaluation items affected by applicable differences in aircraft type design. A.5.2 Level B Differences Training. Level B Differences Training is applicable when operating more than one factory type design model of MU-2B, except the factory type design K and M models and the factory type design J and L models, which may be completed at Level A Training. Level A or B Differences Training is not a recurring annual requirement. Once a person has completed Level A or B Initial Differences Training between the applicable different models, no additional Differences Training between those models is required. When Level B Differences Training is applicable, it should include the following items that apply to the specific difference aircraft models or modification: A.5.2.1 Training. 1.

This training is needed when there are modifications that fall within the definition of Level C Degrees of Differences, as defined in FAA Order 8900.1, Flight Standards Information Management System (FSIMS), Volume 3, Chapter 19, Section 9, subparagraph 3-1314C, Level C Differences. Level C Initial Differences Training should include a record of the Training Course Final Phase Check for evaluation items affected by applicable differences in aircraft type design. Recurrent Differences are applicable to Level C Differences Training items without a record of the Training Course Final Phase Check. When Level C Differences Training is applicable, it should include all items that apply to the specific difference aircraft modification. A typical difference aircraft modification would be installation of an RNAV System, such as a GPS, and would include the following: A.5.3.1 Training. 1. Autoflight: RNAV System use with autopilot or flight director (FD). 2. Electrical Power: sources and distribution. 3.

Level D Differences Training is recommended for part 91 operations (refer to the MU-2B FSB Report for specific Differences applicable to training programs requiring FAA approval apart from part 91 subpart N). This training is needed when there are modifications that fall within the definition of Level D Degrees of Differences, as defined in Order 8900.1, Volume 3, Chapter 19, Section 9, subparagraph 3-1314D, Level D Differences. Level D Initial Differences Training must include a record of the Training Course Final Phase Check for evaluation items affected by applicable differences in aircraft type design. Recurrent Differences are applicable to Level D Differences Training items with a record of the Training Course Final Phase Check. When Level D Differences Training is applicable, it should include all items that apply to the specific difference aircraft modification.

A.6.1 What Are the Training Course Final Phase Check Requirements? A.6.1.1 Completion of the MU-2B training program requires successful completion of a Training Course Final Phase Check taken in the MU-2B airplane or a Level C or D simulator for Initial/Transition Training. The Training Course Final Phase Check for Requalification or Recurrent Training may be taken in ### Page 31 Appendix A A-25 the MU-2B airplane, a Level C or D simulator, or in a Level 5 or 6 FAA-approved MU-2B FTD. The Training Course Final Phase Check must be conducted by a qualified flight instructor who meets the requirements of part 91 subpart N. Simultaneous training and checking is not allowed for Initial/Transition Training. A.6.1.2 For pilots operating under 14 CFR part 135, checking must be done in accordance with applicable regulations. For the purpose of recurrent testing in part 135, § 135.293(b), the MU-2B is considered a separate type of aircraft. A.6.1.3 The Training Course Final Phase Check must be conducted using the standards contained in the FAA Commercial Pilot—Practical Test Standards (PTS) for Airplane: Airplane Multiengine Land and Instrument Rating. A.6.1.4 The Training Course Final Phase Check portion of the training is comprised of the following tasks for all airmen (instrument rated and non-instrument rated). An (*) indicates those maneuvers for Initial/Transition Training which must be completed in the MU-2B airplane or a Level C or D simulator. 1. Preflight Check. 2.

The Maneuver Profiles are provided to develop pilot proficiency with the procedures and techniques contained within this MU-2B flight training program. 2. Though constructed for use in the airplane, they may also be used in the FTD. When an FTD is used, a maneuver may be performed at lower altitudes or carried to its completion. When training is conducted in the MU-2B airplane, all maneuvers must be performed in a manner sufficient to evaluate the performance of the student while never jeopardizing the safety of the flight. A.7.1 What Considerations Should be Made for the Maneuver Profiles? A.7.1.1 Engine Performance. The following should be considered in reference to power settings and airspeeds: 1. Power settings shown in italics are provided as guidance only during training, and are not referenced in the AFM. Power setting guidance is provided to show the approximate power setting that will produce the desired airspeed or flight condition. Actual power settings may be different from those stated and should be noted by the instructor and student for reference during other maneuvers. Power settings in the profiles are stated in torque or pounds per square inch (psi) and will vary with aircraft model, engine model, weight, and density altitude. Power settings are based on standard atmospheric conditions. 2. Some pilots prefer to set power initially using fuel flow, because the fuel flow system is not field-adjustable. Fuel flow settings refer to engine operations only. If fuel flow is used to set power for takeoff, check torque and temperature after setting fuel flow and adjust torque or temperature, whichever is limiting, for maximum takeoff power prior to liftoff. 3. Improperly adjusted torque or improperly calibrated temperatures are a safety of flight issue and must be checked and corrected prior to conducting flight training. 4. The pilot should refer to the performance section of the AFM to determine actual speeds required for his or her particular model and specific weight for any given operation. A.7.1.2 In-Flight Maneuvering. 1. Maneuvers conducted at altitude, such as stalls and steep turns, must always be preceded by clearing turns, and at least one crewmember must continually clear the flying area during the maneuver. The instructor must emphasize the importance of clearing the area, even if the maneuvers are being done in an FTD ### Page 35 Appendix A A-29 or simulator. This will create the habit pattern in the pilot to clear the area before practicing maneuvers. 2. During stalling maneuvers and upon recognition of the indication of a stall, the pilot must call the stall to the instructor and then proceed with the recovery. In addition, during training, the pilot must announce the completion of the stall recovery maneuver. Instructors must exercise caution when conducting stall maneuvers and be prepared to take the controls if the safe outcome of the maneuver is in doubt. 3. During stall maneuvers, it is important that the instructor pay close attention to the position of the balance ball throughout the maneuver and recovery. Stall recognition and recovery is the completion criteria, although the stall in the training and proficiency check phases should progress past initial recognition (stick shaker). For training purposes, stall recovery procedures must include an at the “onset (buffeting) stall condition.” At this condition, the stick shaker will have already been actuated. Caution must be exercised to ensure a safe recovery by positively reducing the AOA and accelerating prior to addition of power. Minimization of altitude loss is not a consideration in evaluating these maneuvers. AC 120-109 should be used as the guidance to completion of stall recognition and recovery maneuvers. 4. When demonstrating a loss of directional control with one engine inoperative, the engine failure must only be simulated. During the slowing of the aircraft to demonstrate loss of directional control, the instructor should use the rudder block method to allow the student to experience the loss of directional control associated with VMC, at a speed of approximately 10 knots above actual VMC. Note: To accurately simulate single-engine operations, zero thrust must be established. The zero thrust torque setting will vary greatly from model to model. It is important to establish to zero thrust torque setting for your aircraft. This requires that the aircraft be flown on one engine to establish the zero thrust setting. This is accomplished by establishing single-engine flight with one propeller feathered and noting the performance with the operating engine at maximum torque or temperature. It is suggested that two airspeeds be established for zero thrust power settings. They are 120 knots, flaps 20 degrees, gear up for takeoff; and 140 knots, flaps 5 degrees, gear up for in-flight and approach maneuvering. Once performance has been established and recorded for each airspeed, restart the other engine and find the torque setting that duplicates the performance (climb or descent rate, airspeed) as was recorded with that propeller feathered. This torque setting will be zero thrust for the simulated inoperative engine. The student/pilot should note that the performance experienced with one ### Page 36 Appendix A A-30 engine operating at flight idle may produce greater performance than if the engine were stopped and the propeller feathered. 5. Premaneuver briefings for any maneuver that requires either an actual engine shutdown or a simulated engine failure must be undertaken when using an aircraft. In the case of an actual engine shutdown, the aircraft must be operating at a minimum altitude of 3,000 feet above ground level (AGL), and the maneuver must be done in a location where a safe landing can be made at an airport in the event of difficulty. A.7.1.3 Takeoff and Landing. 1. When using the profiles to establish the procedure for configuring the aircraft for takeoff or landing, it is important to understand that each task for the procedure, as noted on the procedure diagram, establishes the point at which each task should have been completed and not the exact point at which the task should be completed, unless otherwise stated in the task box. Numbers which represent performance, such as descent rates or other maneuvering information that is not contained in the AFM, are shown in italics. 2. In all takeoff profiles, the prompt for the gear to be retracted is “No Runway Remaining, Gear Up.” This should set the decision point for making a landback after an engine failure and should normally be reached at altitudes of less than 100 feet AGL. It is impractical to attempt a landback from above 100 feet AGL because it can require distances of up to 10,000 feet from the beginning of the takeoff run to bring the aircraft to a stop. Although, even on very long runways, landback will not be necessary above 100 feet AGL and above best single-engine rate-of-climb speed (VYSE) for the flap configurations, if the single-engine climb capability found in the charts in the Pilot Operating Manual (POM), with the gear up, is positive (250 feet per minute (fpm) or better) and obstacles clearance is not an issue. 3. The manufacturer’s FAA-accepted checklists describe a procedure for the discontinuance of flight following an engine failure after takeoff and the realization that the aircraft cannot climb. The corresponding flight profile in this training program is “Takeoff Engine Failure, Unable to Climb.” This maneuver must not be attempted in the aircraft, but must be the subject of a classroom discussion or be demonstrated in the FTD. 4. The focus of all landing procedures, whether two engine or engine out, is on a stabilized approach from an altitude of 500 feet. This will not be possible for all approach procedure maneuvering, especially during NPAs or circle-to-land approaches. Approach ### Page 37 Appendix A A-31 procedures for these two approaches should be stabilized from the point at which the pilot leaves the MDA for the landing. 5. When performing one engine inoperative approaches, landings, or missed approaches, the instructor must be prepared to add power to the simulated failed engine at the first sign of deteriorating airspeed or other situation that indicates the student’s inability to correctly perform the maneuver. 6. While maneuvering in the pattern or during instrument approach procedures with one engine inoperative, a 30-degree bank angle must not be exceeded. This will become especially important when executing NPAs and circle-to-land approaches. A.7.1.4 Emergency and Abnormal Procedures. 1. During training, either in the FTD or in the aircraft, the performance of emergency and abnormal procedures is critical to the completion of the training program. All emergency and abnormal procedures should be simulated when training in the MU-2B airplane. 2. When presenting emergency scenarios to the student, the instructor must not introduce multiple emergencies concurrently. 3. When practicing simulated engine failures, the instructor should also train engine failures under low power conditions. Detection of an engine failure under low power conditions, such as when slowing to approach speeds, can be more difficult to detect and attention to the identification of, and reaction to, a failed engine under low power conditions should be practiced. It may be prudent when experiencing a low power engine failure, such as when in close proximity to the final approach fix, to execute a missed approach as described in the single-engine missed approach profile A.7.1.5 Scenario-Based Training (SBT). SBT creates an environment of realism. The SBT programs utilize a highly structured flight operation scenario to simulate the overall flight environment. The pilot is required to plan a routine, point-to-point flight, and initiate the flight. During the conduct of the flight, “reality-based” abnormal or emergency events are introduced without warning. Because the pilot is constantly operating in the world of unknowns, this type of training also builds in the “startle factor,” and, just as in the real world, the consequences of the pilot’s actions (decisions, judgment, airmanship, tactile skills, etc.) will continue to escalate and affect the outcome of the planned flight. Although flying skills are an integral part of this type of training, SBT enables the pilot to gain experience in dealing with unexpected events and, more importantly, further enhances the development of good judgment and decisionmaking. ### Page 38 Appendix A A-32 A.7.2 How Are the MU-2B Maneuver Profiles Structured?
